This MIB module defines a set of objects for monitoring the Visual Quality Experience Server (VQE-S) operational status. VQE-S receives the channel lineups from the VQE Channel Provisioning Tool. Each channel is uniquely identified with a Service Delivery Protocol (SDP) description, including: - IP multicast address - Real-Time Protocol (RTP) port number - Real-Time Control Protocol (RTCP) port number - Unicast feedback target address - RTP and RTCP port numbers VQE-S supports Error Repair (ER) and Rapid Channel Change (RCC) technologies to improve the delivery of IPTV video services. When a VQE client (VQE-C) notices a missing packet or a group of missing packets, it sends an RTCP Feedback Generic NACK to the VQE-S. The VQE-S looks into its cache, and if it has any of the requested packets, it sends them immediately to the VQE-C as RTP retransmission repair packets. When the VQE-C detects a channel change, it immediately sends an RTCP Picture Loss Indication (PLI) NACK to the VQE-S to request the information for the VQE-C to recover its picture. Both ER and RCC are unicast retransmissions.
